This study sought to investigate the arguments that ecologists engage in as part of their work and to compare their arguments with the way in which ecological arguments have been presented in school argumentation tasks. Ten ecologists, in subfields ranging from individual/behavioral ecology to global ecology, participated in semistructured…

To develop scientific literacy, elementary students should engage in knowledge building of core concepts through scientific practice (Duschl, Schweingruber, & Schouse, 2007). A core scientific practice is engagement in scientific modeling to build conceptual understanding about discipline-specific concepts. Yet scientific modeling remains…

Next Generation Science Standards (NGSS) call for integrating knowledge and practice in learning experiences in K-12 science education. "PlantingScience" (PS), an ideal curriculum for use as an NGSS model, is a computer-mediated collaborative learning environment intertwining scientific inquiry, classroom instruction, and online…

Error in science is a prime occasion to teach the nature of science, especially the central feature of tentativeness. Error types also reflect corresponding methodologies of science, critical for practicing science and (in a context of scientific literacy) analyzing its claims. Effective efforts in teaching about error will ideally be informed by…

I profile here a prospective method for assessing nature of science (NOS) knowledge, as an alternative to VNOS and similar approaches. Questions about cases in contemporary news and from history probe scientific literacy in context. Scoring targets how "well informed" the analysis is, based on identifying relevant NOS information and interpreting…

For many decades, science educators have asked, "In what ways should learning the content of traditional subjects serve as the means to more general ends, such as understanding the nature of science or the processes of scientific inquiry?" Acceptance of these ends reduces the role of disciplinary context; the "Footprints Puzzle" and Oregon's…

Typically, the scientific method in science classrooms takes the form of discrete, ordered steps meant to guide students' inquiry. In this paper, we examine how focusing on the scientific method as discrete steps affects students' inquiry and teachers' perceptions thereof. To do so, we study a ninth-grade environmental science class in which…

This study sought to identify prominent features of the nature of science (NOS) embedded in authentic scientific inquiry. Thirteen well-established scientists from different parts of the world, working in experimental or theoretical research, in both traditional fields such as astrophysics and rapidly growing research fields such as molecular…

This review examines 105 empirical studies that investigate students' views of the nature of science (VNOS), effects of curricular interventions on changing students' VNOS, and relations between VNOS and demographics, majors, and learning of science. The reviewed studies can be categorized into three theoretical frameworks: the unidimension, the…

This article explores the relation between how scientific knowledge is created and the reasoning involved in learning content with understanding. Although an asserted parallel between these underpins reform, little is actually known about this relation. This article offers a model of this relation that draws coherent connections between the…

Thirty fourth-grade students participated in an extended intervention previously successful in fostering skills of scientific investigation and inference, notably control of variables (COV). The intervention was similarly successful for a majority of students in the present study, enabling them to isolate the three causal and two noncausal…

D. Klahr and M. Nigam (2004) make a case for the superiority of direct instruction over discovery learning in students' mastery of the control-of-variables strategy central to the scientific method. In the present work, we examine acquisition of this strategy among students of the same age as those studied by Klahr and Nigam, as well as follow…

One hundred years after its conception, the scientific method continues to reinforce a kind of cultural lore about what it means to participate in inquiry. As commonly implemented in venues ranging from middle school classrooms to undergraduate laboratories, it emphasizes the testing of predictions rather than ideas, focuses learners on material…

Pleads that authors distinguish between process" as an end of science instruction (knowledge about how scientists work), and process" as a means of instruction (students investigating, measuring, observing, reading, etc., in the manner of scientists). (AL)
